Fun quest! Always game for more Cy content, and the song was fantastic! The thing that was the biggest step forward to me in terms of design language was the part where you got to practice with the Shadow during the musical number. One thing that Warframe has lacked since its inception is any sort of hands-on tutorial for frames, or even a "try before you buy" mode where you can experiment with powers and their interactions. Now I'm not saying each frame needs a bespoke training area with a fully produced shanty accompaniment, but this showed (to me, at least) that you can get a sufficient feel for a frame's basic rhythm with just an empty room, basic prompts and some paper targets - might be something to look into down the road for the Codex's frame section?
